to ensure that tape does not shed into hydraulic system, causing damage.
Trim loose ends.
2. Install a pressure gauge in-line from the pump for added safety and better
control.
3. Connect the hose(s) to your cylinder or tool.
OPERATION
Before Using the Pump
1. Check all system fittings and connections to be sure they are tight and leak free.
CAUTION
NEVER add extensions to pump handle. Extensions
cause unstable pump operation.
Using Two-Speed Pumps
These pumps provide 2-stage flow. Under no-load, the pump operates in the high
flow first stage for rapid advance. When the load is contacted, the pump
automatically shifts to the second stage for building pressure. For P140 or
P140D models, when pump reaches approximately 600 PSI, you must
momentarily stop pumping and raise the handle to shift to the high pressure
stage. After the pump shifts, pumping takes less effort
Single-Acting Applications with Release Valve
1. Close release valve by turning clockwise, as shown in Figure 1.
2. Operate pump handle to deliver hydraulic power to system. Pressure will be
maintained until release valve is opened.
3. Open release valve (turn counter-clockwise) to release pressure, allowing oil
to flow back to the reservoir.
Double-Acting Applications with 4-Way, 3 Position Manual Valve
Pumps with 4-way control valves are designed to operate double-acting cylinders.
